LUBRICATING DEVICE FOR VEHICLE-WHEELS.

SPECIFICATION forming part of Letters Patent N 0. 717,269, datedDecember 30, 1902. Application filed September 13 1902. Serial No;123,289. (No model) To all whom it may concern:

Be it known that I, WILLIAM F. PROBST, a

citizen of the United Statesresiding at Chillicothe, in the county ofRoss and State of Ohio, have made certain new and useful Irnpro'vementsin Lubricating Devices for Vehicle-Wheels, of. which the following is aspecification.

My invention is an improvement in lubrieating devices forvehicle-wheels; and it consists in certain novel constructions andcornbinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is aside elevation of a wheel embodying myinvention. Fig. 2 is a similar view of the central portion of the wheel,the slide-plate being removed. Fig.

3 is a detail view of the removed slide-plate from the inner sidethereof, and Fig. 4 is a cross-section on about line 4 4. of Fig. 1.

The wheel, as shown, includes the rim A, which is connected by thespokes B with the spoke-ring O. This ring 0 encircles the hub D and isspaced apart therefrom to receive the cushion-ring E, which bearsbetween the hub D and the spoke-ring C and cushions the wheel, as willbe understood from Figs. 1, 2, and 4. The hub D has a central opening Dfor the shaft or axle and may turn on the axle when used on ordinaryvehicles or may be fixed to the axle when used on automobiles. At itsouter edges the hub is rabbeted at D to receive the inner edges of theslide-plates F and G, which are fitted at their inner edges in the saidrabbets and secured by means of screws H or in any suitable manner. Inits outer edge the hub D is grooved at d to receive the cushion E, whichcushion may be a ring circular in cross-section and of rubber or similarresilient material, as will be understood from Figs. 2 and 4.

By the described construction it will be noticed the weight exerted onthe hub D will be yieldingly borne by the rim of the wheel through thespokes and spoke-ring O, and in order to retain the latter in properrelation to the hub and also to secure the spoke-ring to v turn with thehub I employ the side plates F and G, which are secured at theirinneredges to the hub and lap alongside the cushionring E and the spoke-ringO and slide along the said spoke-ring, as will be understood from Fig.4. One of the side plates G is provided near its outer edgewith aninwardlyopening radially extending groove G, in which operates aprojection I on the side of the spoke-ring, such projection I beingpreferably a roller journaled on a screw or stud J to reduce friction asthe side plate G travels along the side projection I. This roller I, itwill be seen, operates to cause the spoke-ring to turn with the hub andyet does not interfere with the radial sliding of the plate G wheneverdesired. It will also be noticed that the outer end of the radial grooveG is closed at G and the spoke-ring O is provided adjacent to the grooveG with a radially-projecting plate which extends to the outer end of thegroove G and overlaps the end closure G and operates to prevent dust andthe like from entering the groove G in all adjustments of the parts.This is an important feature of my invention, as by means of the radialprojection O, I protect the groove G at all times from ingress ofobstructions and so insure the parts being in condition to operate asdesired at all times.

As the plates F and Gslide upon or against the opposite edges of thespoke-ring C, it is important to provide means for lubricating the jointbetween the plates F and G and the ring C. To this end I provide groovesK and L in the opposite side faces of the spoke-ring O and extendingaround the said ring and communicating with an oil-feed passage M incommunication with the oil cup N, supported on the spoke-ring O, asshown in Figs. ll, 2, and 4:. It will also be noticed the oil-groove Lis overlapped by the roller I and extends to the stud J, forming abearing for the said roller, so the groove L will supply lubricant torelieve friction between the roller I and its bearing J and between thesurface of said roller I and the walls of the groove G. By this means Iso arrange thelubricating devices as to supply the lubricant to thesliding bearing between the ring O and the, side plates F and G, andalso to lubricate both the surface and the journal of the roller I, asbethe wheel, and that the parts are so constructwhen assembled for use.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Theimprovementinwheelssubstantially as herein described, comprisingthe hub grooved in its outer edge and provided in its opposite faces atits outer edge with the an nular rabbets, the slide-plates secured attheir inner edges in the said rabbets and projecting outwardly from thesaid hub, one of said slide-plates being provided with theradially-extending groove in itsinner face, said groove being closedatits outer end, the cushion-ring seated in the groove of the hubbetween the said slide-plates, and the spokering fitting between theslid e-plates and upon the cushion-ring and provided with an oilfeedpassage and at its opposite faces with oil-grooves extending around thering and supplying lubricant to the bearing between the sides of thespoke-ring and the slideplates, and said spoke -ring being provided withthe radially-projecting plate overlapping the groove in the slide-plateand extending to the closed outer end thereof, and the roller journaledto the spoke-ring and overlapping the oil-groove in the side thereof,and operating within the groove of the slide-plate, substantially as andfor the purposes set forth.

2. The combination in a vehicle-wheel, of the hub and the slide-platesfixed in connection therewith and projecting outwardly from the same,the spoke-ring operating between the said side plates and provided inits opposite faces with annular oil-grooves for lubricating the bearingbetween the side plates and the said ring, and also having means wherebyoil may be supplied to the said grooves, and the cushion operatingbetween the spoke-ring and the hub, and between the opposite sideplates, substantially as and for the purposes set forth.

3. The combination of the hub, the spokering, the cushion between thesame, and the sliding side plates on opposite sides of the hub andspoke-ring,means whereby the spokering is held to turn with the hub anddevices for supplying lubricant to the inner faces of the slide-plates,substantially as set forth.

4. The combination of the hub, the cushion thereon, the spoke-ring onthe cushion and provided with a laterally-projecting roller and in itsface with an oil-groove overlapped by said roller, and a slide-platefixed in connection with the hub and sliding along the grooved face ofthe spoke-ring and having a radially-extending groove to receive theroller of the said ring. all substantially as described, whereby theoil-groove may operate to feed oil to lubricate the roller and may alsolubricate the sliding bearing between the spokering and the plate,substantially as set forth.

5. The combination of the hub, the slideplates on the opposite ends ofthe hub and projecting radially from the same and spaced apart, thespoke-rin g operating between said slide-plates and provided with thespokes and having at its opposite sides the annular grooves, means forsupplying lubricant to said grooves, devices connecting the hub-ringslidably with the slide-plates and including a projection crossing oneof the grooves in the spoke-ring, and cushioning devices between thespoke-ring and the hub, substantially as set forth.
